Why is my kia optima not starting?

I recently replaced my battery, but it still won’t provide enough power to crank the engine. I have also tried jump-starting your car to see if this fixes the problem but it has also failed.

Hey there, sorry to hear about the trouble with your Kia Optima. Dealing with car issues can be frustrating. I’ve had a similar experience with my car before, and it turned out to be a problem with the alternator. The alternator is responsible for charging the battery while the engine is running, so if it’s not functioning properly, even a new battery won’t hold a charge for long.

Another possibility could be a faulty starter or starter relay. If the starter isn’t engaging properly, it won’t be able to crank the engine, no matter how much juice your battery has.

Of course, diagnosing car problems can be tricky without actually seeing the vehicle, so it might be a good idea to take it to a trusted mechanic or dealership for a professional inspection. They’ll have the tools and expertise to pinpoint the exact issue and get you back on the road in no time.


It sounds like there could be issues beyond the battery. Check your starter motor and alternator. If those seem fine, there might be electrical system problems. Consider getting a professional diagnosis to pinpoint the exact issue.
